Yes but Just for example we have shown only 3 data points and as per our requirement data will be not fixed to certain period of time. it should be day/month/year for 1 or more data points will be there.
Ideally, it should show connected line otherwise if user want to drill down from year to month and navigate in month range then it will not showing connected line then don't get properly.
For example: User drill down to 2017 and then Jan-17 having data then Dec-17 having data then user can't show connected line in it to show progress..
